CORNER BRAGE FOR CHAIR SEAT FRAMES.

coRNER-BRA'CE FOR CHAIR-SEAT FRAMES.
To all whom it may concern Be it known that 1, WILLIAM P HEBERGER, a citizen of the United States, resid' at Cincinnati, in the county of Hamilton, in the State of Ohio, have invented certain new'and useful Improvements in Corner-Braces for Chair-Seat Frames; and I do hereby declare.
that'the following is a full, clear, and exact description of the invention, which will en-'v able others skilled in the art to which it appertains to make and use. the same, reference being had to the accompanying drawings, which form part of this specificationi My invention relatesto improvements in corner braces for chair seat frames.
It is well known that in that class of chairs having box-seats, 0r ,-s'eats formed of four. seat rails in right-angular relation it is necessary to brace the corners of the seat-frame to secure the necessary strength, rigidity, and durability; that the wooden blocks now uni versally used for that purpose are secured in position either by glue, nails, or by mitering, and are subject to shrinka e when not thoroughly seasoned, thereby estroying the adhesive power of the glue and loosening the nails, and thus neutra 'zing their elucienc y as a brace; and that even when seasoned wooden blocks swell and shrink by exposure to dampness and long continued dry heat, thereby loosening them and materially counteracting their function and utility. as an aid to the strength and rigidity of the chair-seat.
' The primary purpose therefore, of my present invention is to provide an improved .corner brace for chair seat frames of simwhich it is employed.
My invention consists of stamped sheetmetal corner brace bent into angle-iron form with its ends s lit on the line of fold, and provided upon t 'e'ir inner faces with integral prongs ada ted to engage, and rigidly brace both latera ly and vertically the adjacent right angular sides of the chairseat frame at its corners.
In the accompanying drawings similar ref- Specification of Letters Patent.

erence numerals indicate like parts throughout the several views in which Figure 1 is a fragmentary perspective view of one corner of an inverted chair seat frame having my invention mounted in position thereon, showing therelative arrangement of its coacting parts. Fig. 2 is an enlarged p'er- I spective detail of my invention in the position shown in Fig. 1, showing the relative arrangement of the cooperating split ends and the holding spective o e same in an inverted position ,to more clearly show the integral barbs or in any proper manner. To the upper face of these pieces 3 is secured the chair seat 4 of leather, cane, or any other suitable or desired material.
In diagonal relation to the four corners of the chair seat frame, my improved brace a1- ranged as shown in Fig. 1, is formed of one piece of sheet metal, preferably by stamping 1 and has two coacting sides in right angular relation. The horizontal side 5 of the brace has the end thereof formed into an acute angle to correspond with the converging sides of the seat-frame to which they are secured, and has the edges of these ends turned at right-angles thereto and provided upon their inner face with a series of terminal teeth, barbs or prongs 6 of any desired form or dimensions. The side 5 also has one or more integal barbs or prongs 7, preferablyrtwo in... num er, stamped or cut therefrom near its ends and bent into right-angles therewith to cooperate with the teeth 6 in the manner hereafter described. These prongs or barbs 7, triangular in contour, are preferabl but not necessarily of somewhat greater Icngth than the teeth 6, as shown in Fig.3.
The adjacent vertical and integral side-8 of the brace has its ends severed from the plate 5 on the line of the fold 9 and bent into an acute angle therewith to conform to the rela- 9 65 rongs thereon. Fig. 3 is a per tions is provided upon its inner face with v a pair of opposite integral terminal prongs or barbs 11 adapted to holdingly engage the said vertical side of the adjacent seat rail in use. v
The manner of employing my improved brace thus describedis 'obviousandbriefly stated is as-follows: At any proper stage of, the manufacture of a chair of the class speci-- fied, and afterthe seat frame has been com-. pleted, the operator inverts the chair, places one of my improved angle-iron braces acrossv each corner of the seat frame, as shown in Fig. 1, and by pressure or other proper man ner forces the brace'home to its diagonal position, with the'teeth 6 and 7 of the side 5 inserted into the lower edge of'the seat rail 1 and the teeth 11 of the-ends 10 of the side 8 embedded in the adjacent vertical sides of the said rails, whereby the four seat rails are rigidly braced both laterally and vertically at each corner of the seat frame.
If it is desired the ends 10 ca; be further secured in position by inserting a small nail in each of the apertures 12 therein; though it has been found by tests and experience that their use is unnecessary.
It is obvious that by the use of my inverithe use of wooden corner braces is eliminated.
Having thus described my. invention and the manner of employing the same, What I desire to secure by Letters Patent is:
s In a chair seat, a corner brace made of sheet metal bent into angle form, and having.
its opposite ends slit on the line of the fold, one side of the angle being horizontally disposed and having its ends attached to the horizontal portions of the seat rails, the other side of the angle being vertically disposed "and having its-ends bent outuat an angle theretoand ,.secured to the inside vertical sides of'the seat rails.
Signed by me at Cincinnati, in the county of-Hamilton, and Stateof Ohio, this 3d day of November, A. D. 1906.
